24, and working at a frozen yogurt shop?

I know times are rough, and the job market hasn’t improved much, but I’m having a hard time finding a job working with animals, or they just take too much time to make a final decision (patience is a virtue, I know) but I’m yearning to just get out of my moms house. We don’t get along at all, and it just keeps escalating to physical fights. But anyway I did do well at a recent interview at a frozen yogurt place, and I start training soon…is this too much of a juvenile job for a 24 year old? I know for sure that everyone I will be working with are in the age range of 17 to 18. I kinda feel loser-ish.
